By default, we enable NGINX Direct Delivery for all sites on our servers, which means that certain items, like your images, will load faster and will be directly served by NGINX. However, the biggest impact on the WordPress loading speed is achieved by using the higher levels of our SuperCacher service. This connects your site with our NGINX-based dynamic cache and Memcached service available on all hosting plans. For online stores specifically, where dynamic caching may be a problem for shopping cart behavior, we cleverly monitor whether users have items in their cart and exclude them from caching.
